Draws the projection of a given path upon the surface defined by the given geo pyramid. In effect, this function will go through each absolute geographic coordinate in a path, transform this into the local vertical coordinate system for the specified dataset, and then produce glVertex2f() calls for the resulting 2d (x,y) coordinates. Note, these coordinates are with respect to the origin of the dataset. This function was produced for drawing 2D lines over a digital map.
